GlobalBuildingAtlas: first complete global dataset of building polygons, heights, LoD1 3D models
anselm · x · 2026-11-01
Published in ESSD, GlobalBuildingAtlas is the first dataset with complete worldwide building polygons, heights, and LoD1 3D models, built exclusively from optical satellite imagery. Trained on 168 cities with LiDAR reference, it achieves height RMSE of 1.5–8.9 m across continents (5.5 m global average), fuses OSM/Google/Microsoft/PSR footprints into one consistent global layer, and outperforms existing global height products on completeness and volume accuracy across 28 validation cities. Openly available.
